About Piston Auto

Family-owned and operated in Carroll County. We built this shop on one principle: treat every car like it's our own.

OUR STORY

Built on Trust, Driven by Excellence

Ray Delgado runs Piston Auto on a simple promise: honest work at a fair price. It's a full-service shop with 8 bays, 12 lifts, and a team of specialists who treat every vehicle like their own.
